ALBERT E. KERFOOT, OF BLACK POINT, FLORIDA.

MUSIC-HOLDER AND LEAF-TURNER.

To all whom it may concern:

Be it known that I, ALBERT E. Knnroo'r, a citizen of the United States, residing at Black Point, in the county of Dade and State of Florida, have invented new and useful Improvements in Music-Holders and Leaf- Turners, of which the following is a specification.

My invention relates to music holders and leaf turners, and one of its objects is to provide a novel and highly useful music holder which is simple and durable, and which may be manufactured and sold at a comparatively low cost.

A further object of the invention is to provide a novel escapement by the operation of which the, leaves are freed to be turned consecutively, one wherein provision is made for permitting all of the leaves to be turned to their normal position at the same time, and one which is simple of construction and easy of operation.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter fully described, claimed and. illustrated in the accompanying drawings, wherein:

Figure 1 is a view in front elevation of a music holder and leaf turner, constructed in accordance with my invention. Fig. 2 is a view on an enlarged scale of a fragmentary portion of the base of the music holder, the same illustrating the manner in which the escapement is operated to release one of the swinging arms. Fig. 3 is a sectional view on the line 3-3 of Fig. 1, looking in the direction indicated by the arrow. Fig. 4 is a sectional view on the line 44 of Fig. 1.

Referring to the drawings by reference numerals, 1 denotes a base, 2 vertical end standards, 3 a vertical central standard and 4 horizontal connecting bars, all being suitably united and braced to provide a holder for a music book.

In practice, a music book is secured to the center standard 3 by any suitable means, and rests upon a shelf 5 which is disposed horizontally and secured centrally of the base 1. The opposite ends of the base are turned up to provide horizontally disposed shelves 6, said shelves 6 being alined with the shelf 5, and adapted to form rests for the outer edges of the cover of the music book. Brackets 7 are secured to the base 1 directly beneath the shelf 5, and are spaced apart for Specification of Letters Patent.

Application filed November 7, 1905.

Serial No. 286,237.

the reception between them of a suitable shaft, not shown. Swinging arms 9 have their inner ends formed to provide hub portions 10 which are mounted upon said shaft to permit the arms 9 to be swung automatically from right to left to consecutively turn the sheets of the music book. The swinging arms 9 are held normally on the left side of the holder by means of elastic members 11, each of which has one of its ends secured to one of the swinging arms and thence passed around the hub portions 10 thereof, after which the other end of said member is secured to the base. The free ends of the arms 9 are provided with upstanding clamps 12 for engagement with the lower edges of the music sheets in order that the swinging of each arm will turn one sheet of music. The arms 9 are held on the right side of the music holder and released one at a time to permit them to be swung consecutively to the left of the music holder by means of an cscapement which comprises members or levers 13 and 14.

The lever 13 is pivotally mounted upon a projection 15 secured to the base 1, and it is yieldingly held in horizontal position by means of an elastic member 16 to retain its end 13 out of the path of the movement of the arms 9. The elastic member 16 has one of its ends secured to the lever 13 at a point to the right of the pivot and its other end secured to the upper face of the projection 15, whereby when the force which swung the end 13 of the lever 13 upward into the path of the movement of the arms 9, which force should be applied to the enlarged end 13 of the lever 13, is removed the elastic member 16 will swing the end 13 of the lever downward out of the path of the movement of the arms 9. This downward movement of the end 13 of the lever is limited by a stop 17 which is secured to the face of the projection 15 in the path of the movement of the end 13 of the lever. The lever 14 is-pivotally secured to the lever 13 at a point to the right of the pivot of said lever. The lever 14 is yieldingly held at an acute angle with relation to the lever 13, or to the right of the vertical, to position its end 14' in the path of the movement of the arms 9 by means of an elastic member 18, which has one of its ends secured to the lever 14 at a point below its pivot and its other end to the lever 13 at a point to the right of the pivot of the lever 14. The end 14 of the lever 14 is adapted to be swung to the right of the vertical out of the path of the movement of the arms 9, when it is desired to place them behind the escapement. The elastic member 18 returns the lever to its normal position, that is, returns its end 14 into the path of the movement of the arms 9 when the force which moved the end 14 of the lever to the right of the vertical out of the path of the movement of the arms 9 is removed, and which force should be applied to the enlarged end 14 of the lever 14.

It should be apparent that the end 13 of the lever 13 is yieldingly held in a horizontal position out of the path of the movement of the arms 9 by means of the elastic member 16, and that the end 14 of the lever 14 is yieldingly held to the right of the vertical in the path of movement of the arms 9 by means of the elastic member 18. Nith the levers of the escapement in this position, the arms 9 are held on the right of the music holder by means of the end 14 of the lever 14, and the end 13 of the lever 13 is positioned to be moved upward in rear of the advance arm 9 and in front of the next adjacent arm. When it is desired to release one of the arms 9, force is applied to the end 13 of the lever 13 to swing the end 13 upward in rear of the advance arm and in front of the next adj acent arm and to move the end 14 of the lever 14 to the right of the vertical and out of the path of the movement of the arms 9. As the end 14 of the lever 14 is moved out of the path of the movement of the advance arm, said arm is free to be returned to the left of the music holder by means of the elastic member 11 connected therewith. The next adjacent arm is prevented from being swung to the left of the holder by means of the end 13 of the lever 13. When the force which moves the levers into this position is removed, the elastic member 16 swings the end 13 of the lever 13 downward out of the path of the movement of the arms 9 and swings the end 14 of the lever 14 into the path of the movement of the arms. It is to be understood that the end 14 of the lever 14 is moved into the path of the movement of the arms 9 just previous to the movement of the end 13 of the lever 13 out of the path of the movement of the arms, and that the end 14 of the lever 14 is moved into the path of the movement of the arms just previous to the movement of the end 13' by the lever 13 out of the path of the movement of the arms. The elastic member 18 yieldingly retains the lever 14 in such relation to the lever 13 that any movement imparted to the lever 13 will cause the lever 14 to correspondingly move. After all of the arms 9 have been swung to the left of the holder and it is desired to again retain the same behind the escapement for liberation one at a time, the lever 13 is held from movement by a portion of one of the hands of the operator and the thumb of said hand is employed to press the end 14 of lever 14 to the left against the resistance of the elastic 18, whereby lever 14 will be swung independently of lever 13 to move its end. 14" to the right of the vertical out of the path of the movement of the arms. After the arms have been swung to the right of the holder by the other hand of the operator, the pressure upon the lever 14 is removed and thereupon the elastic member 13 returns the same to the left of the vertical and. into the path of the movement of the arms 9.

Having fully described and illustrated my invention, what I claim is:

1. In a music leaf turner, the combination with swinging arms, of an escapement comprising a pivotally mounted lever, another lever pivotally mounted upon the first-named lever, means for yieli'lingly retaining the first-named lever out of the path of the movement of the swinging arms, and means for yieldingly retaining the second named lever in the path of the movement of the swinging arms.

2. In a music leaf turner, the combination with. swinging arms, of an escapement comprising a pivotally mounted lever, a shorter lever pivotally mounted upon the first-named lever, means for retaining the longer lever normally out'of the path of the movement of the arms, and means for retaining the shorter lever normally in the path of the movement of the arms.

In testimony whereof, I aflix my signature in presence of two witnesses.

ALBERT E. KER'FOOT.
